Listen to the Stinker Madness Episode
When you take 70-bajillion characters with vague powers and zero characterization, toss in a very poorly cast James Remar who manages to act worse than Christopher Lambert, sprinkle with crappy, boring fight scenes with a side of the worst special effects ever, and then finish off with completely removing any bit of "Mortal Kombating" while still calling it Mortal Kombat, you've built a movie worthy of being called one of the worst movies of all time. Mortal Kombat: Annihiliation deserves to be in the IMDB Bottom 100, should have swept the Razzie awards and deserves to be mentioned alongside Birdemic and Manos: The Hands of Fate. It is a truly awful and painful film to view.
The story of the film truly isn't worth mentioning, mostly because it doesn't exist. The plot entails Shao Kahn (Bryan Thomspon) causing a "convergence" of all the realms so that he can't have power. We can't figure out what that power is or why smashing realms together causes that. So Raiden (James Remar) and team must stop Kahn and his cronies by using Katana as a key, Liu Kang defeating Kahn in a fight and Raiden becoming mortal. That's it. That's the entire plot. No other details are revealed.
